SOLOMON R. VAGG, OF APPLETON, VISOONSIN.

PULP REFINING AND DRESSING ENGINE.

SPECIFICATION forming part of Letters Patent No. 447,853, dated March 10, 1891.

Application filed August 31,1889. Serial No. 322,628. (No model.)

To ctZZ whom, it may concern.-

Be it known that l, SOLOMON R. VAGG, a citizenof the United States, residing at Appleton, in the county of Outagamie, State of lVisconsin, have invented certain new and useful Improvements in Pulp Refining and Dressing Engines for Making Paper-Pulp Fiber, of which the following is a true specification, reference being had to the accompanying drawings.

My invention has for its obj ect the improvenient of the work heretofore accomplished by the plain cone engine, whereby a larger amount and better grade of work is performed and the pulp fibers better and more strongly prepared, so that it can be used in the best classes of writing-paper for clearing from shreds and knots, making long slim fibers of great strength and smoothness.

The general arrangement of parts in a plain taper cone-engine is well known to those skilled in the art. My invention is an improvement thereon. y

The accompanying drawings represent and form part of this specification, reference-letters indicate like parts in the figures.

In the drawings, Figure l represents a vertical longitudinal section through the engine. Fig. 2 is an elevation of the circular plate formed with or affixed to the end of coneshell. Fig. 3 is a partial section showing handwheels for the separate and independent adjustments of the cone and revolving disk and graduated scale and pointers and packinggland between shaft and sleeve and the feather-key for sleeve to move forward and backward upon and cause its revolution. Fig. 4 is an elevation of the adjustable revolving disk F. Fig. 5 is a perspective View, partly in section, showing the general relation of parts.

S indicates the revolving shaft, which is driven by suitable power. A cone G2, having a grinding-surface of the usual character, is attached to the shaft S, so as to revolve therewith. The cone is within the casing G', which has interior grinding-surfaces, as usual.

E is a circular plate or disk, having upon its face numerous knives, as shown in elevation in Fig. 2, and is attached to and made an extension of the ordinary cone-shell.

F is a circular revolving disk fitted to shaft S, with a long sleeve extending to the right through engine-case ending at packing-gland D?. Upon the inside at D is a packing-gland to prevent pulp fiber from working in between the shaft S and the sleeve of revolving disk F. gland D2. This disk is movable upon featherkey K or its equivalent, sliding upon it and shaft S and moved back and forward by operating-screws and hand-wheel O. Handwheel O is attached to shaft c, which has a screw-threaded engagement with nut d on some fixed part ofthe frame. The other end of shaft has a bearing (direct or indirect) against standard e. This standard is pivoted at some fixed point, as g, and bears against collar f. The key or spline K connects collar f to the shaft. A compressible receptacle A, for oil or other uid, is interposed between shaft C and standard e. A pressure-gage B is attached to vessel A. The pressure transmitted through collar f and standard e to the receptacle A will be indicated on gage B, and this indicator shows the pressure on the stock between the grinding-disks. The gage will show the pressure, but may not correctly point out the exact position of disk F. The position will be shown by the index-plate o and a pointer p, either the index plate or VJthe pointer being attached to a fixed part of the machine and the other being attached to a movable part. This index and pointer may be used as an addition to the vgage device heretofore described.

It will be understood that modifications may be made, wherein equivalents are used,

On the outward end is also a packingwithout departing from the spirit of this in- 'vention That I claim isl. The combination, with the rotatingshaft, of a grinding-disk rotating with said shaft, but movable lengthwise thereof, a fixed surface against which said disk bears the material to be ground, and packing-glands surrounding the shaft and covering the central part of the disk, so as to protect the same, substantially as described.

2. The combination, with the fixed grinding-surface, of the rotating shaft, a grindingdisk movable lengthwise thereof and facing the grinding-surface, a standard connected to said disk, substantially as described, and a TOO a gage on which the standard bears, and a screw-shaft resting against said gage, substantially as described.

5. The combination, with the rotating shaft and a fixed grinding-surface, of a disk movable on the shaft With relation to the grinding-surface, and an index or indicator showing the position of the grinding-disk, substan- Jtially as described.
